JONES, OI PROVIDENCE, RHODEISLAND, ASSIGNOR TO UNIVERSAL WIND- ING"GOMPANY, OF BOSTON,MASSACHUSETTS, A CQRIORATION OF MASSACHUSETTS "WINDING momma Applicationfiled August 9', 1928. Serial no. 298,518.

This invention relates to improvements in winding machines for windingsilk, rayon and other delicate strand materials to produce splicerbobbins for use in knitting machines. The improvements. are directedparticularly to that type of machine in which the strand material iswound on a tapered or inclined chase to build a bobbin of generallycylindrical form having a conical or pointed nose from which thematerial delivers.

One object of the'invention is to provide a winding machine having meansfor rotating the cop or bobbin and means for traversing the strandmaterial on the tapered chase thereof, with the traversing-means orguiding-means adapted to follow the inclined surface'on which thewinding is performed without contact therewith.

Another object of the invention'is toprovide means for holding theguiding-means or t hread-guide'in close proximity to the surface onwhich the winding is performed, to, insure an accurate disposition ofthe coils of winding, while avoiding contact of the guide therewith toprevent abrasion or chafing of the delicate strand material.

' Another object of the invention is to provide a controlling-device foroscillating the thread-guide which is operated automatically from thereciprocating movement of the guide Without the use of intervening meanssuch as cranks, eccentrics or the like.

Another object of the invention is to provide a controlling-device forthe traversingmeans or thread-guide which may be applied to windingmachines of standard types without material change in the constructionor arrangement of the parts thereof.

Another object of the invention is to provide a controlling-device forthe travers1ng-= means which is adjustable to properly regulate theaction of the thread-guide in windingv cops and bobbins of differentsizes and shapes.

Another object of the invention is-to provide a device of the typespecified which is simple in construction, eflicient in act-ion and oforder. I

-Further objects of the improvement are set forth in the followingspecification which proof against derangement and getting out machineshowin of the thread-guide controlling-device;

- Fig. ,6 is a fragmentary perspective view showing a modified form ofthe track or rail as provided with adjustable means for regulating itsoscillating movement; and

Fig. 7 is a perspective viewof the element which acts torock the trackto oscillate the thread-guide. I p In the present drawings the inventionis illustrated aslapplied to use on a winding machine of well-known typecomprising the main elements of a rotating winding-spindle, 0

a reciprocable thread-guide, and means for reciprocating thethread-guide to adapt it to traverse the strand material on the cop orbobbin. In other cases, however, the machine may tomprise means forlongitudinally reoiprocating the winding-spindle instead of thethread-guide, and still other forms of construction of the essentialelements of the winding-mechanism may be employed which would fallwithin the spirit and scope of the present invention. In the presenttype of machine the thread-guide is adapted to oscillate on its axis ofreciprocation, 'whereby it is caused to follow the tapered surface ofthe winding, and means are provided for feeding the guide longitudinallyof the bobbin to rogressively advance the layers of winding rom base totip of the bobbin. In other types of machines, however, the advance orste ping forward of the layers of winding may e accomplished by movingthe winding-spindle in an aixial direction with respect to the threadguie.

In Figs. 1 and 2 of the present drawings, 2 designates a box-like frameon which the various elements of the winding-mechanism are mounted, and3 is the rotatable windingspindle shown as journalled in suitablebearings 4 at the top of the frame. A cam-shaft 6, arranged below inparallel relation to the winding-spindle 3, is journalled in bearings 5on the sides of the frame 2, and carried thereon to be driven thereby isa helical traversecam 7. The winding-spindle 3 and cam-shaft 6 may beconnected to be rotated, one from the other, through the use of pulleys,gears or the like, not herein shown, the machine bein driven from asuitable source of power suc as a motor or counter-shaft, not shown.

The winding-s )indle 3 extends be 0nd its hearing at the si e of theframe 2 an is revided with a suitable mandrel or cop-ho der for suporting the bobbin-receiver or tube C on whlcli the winding is to beperformed. As herein shown the winding-mandrel or copholder 8 is ofgenerally cylindrical form, being provided at its inner end with anenlar ed frusto-conical boss 9 for receiving the 1101 ow tapered butt 0of the paper bobbin-receiver or tube C. Any suitable means maybe-employed for holding the bobbin-receiver or tube C on the mandrel 8,this device not being herein shown or described as it forms no part ofthe present invention.

Supported from the cam-shaft 6 of the machine is a traverse-frame 10, onwhich is slidably mounted the traversing threaduide 25 to adapt it to berecipro'cated longitudinally of the winding-spindle 3.The'travelse-frame 10 is constructed with a horizontal cross-bar ormember 11 having opposite depending arms 12 and 13 formed with hubs 14and 15. The hubs 14 and 15 are bored to receive bushings 16, held fixedlin the bearings 5 on the frame 2, and in w ich the cam-shaft 6 is{ournalled to rotate.

A longitudinal y-extending groove 17 in the cross-member 11 of thetraverse-frame 10 provides a horizontal trackway for a slidable bar orrod 18. One end of the rod 18 is connected to a cross-head or slide 19which carries a stud or roller 20 engaging in the helical groove 21 ofthe cam 7. It will be noted by reference to Fig. 2 that the cam 7 issecured fast on the camshaft 6 by means of a key 22 and the rotation ofthe shaft turns the cam to reciprocate the slide 19 and rod 18.

The opposite or forward end of the rod 18 carries an upright arm 23connected to a parallel sliding rod 24, see Figs. 2 and 3, whichconstitutes the traverse-bar for .reci rocatingthe thread-guide 25. Asshown in the present drawings, the traverse-bar 24 is mounted to slidein bearings 26 and 27 formed on a supplemental frame 28 attached to anoverhangin portion 29 of the main traverseframe 10. li teferringparticularly to Figs. 2 and 3, the supplemental frame 28 is constructedwith a rail or bar 30 clamped to an upstanding flange 31 on theoverhanging portion 29 of the traverse-frame 10 by means of screws 32.The lower edge of the rail 30 overhangs the groove 17 in the cross-bar11 and portion 29 of the traverse-frame l0 and is formed with an arcuatebearing face abutting the side of the rod 18 to hold the latter in lacein the groove, see Fig. 3.

he traverse-frame 10, as before stated, is swiveled to swing on the axisof the camshaft 6, being thus mounted to adapt it for adjustment to setthe traverse-bar 24: in proper s aced relation with respe'ct to the axisof t e winding-spindle 3, this adjustment bein altered for windingbobbins of different dlameter as hereinafter more fully explained. Thetraverse-frame 10 is normally held in fixed position by means of adetent lock shown in detail in Fig. 3. Referring to Fig. 2, a horizontalrod 33 extends through the side of the forward arm 12 of thetraverse-frame 10, being further supported in a lug 34 at the end of thetraverseframe extension 29 and also in a lug 35 at the outer end of thesupplementary frame 28. The rod 33 is rockable in its bearings andcarries a weighted detent-arm 36 secured in place thereon b means of aset-screw 37, see Fig. 3. The etent-arm 36 is formed on its inner sidewith a detent-lug or latch 38 which is engageable with a shoulder 39 ona fixed locking-member 40. The lo'ckin -member 10 is of arcuate form andprovide with a slot t1 for receiving a bolt 42 by means of which thelock is fixedl clamped to the side of the frame 2. The ocking-member 40may be adjusted in position by loosening its bolt 42 whereby to properlylocate the detent-shoulder 39 to hold the traverse-frame in fixedposition with the traverse-bar 241 in predetermined relation to thewinding-spindle 3.

The lug or latch 38 on the detent-arm 36 may be released from thedetent-shoulder 39 by rockin the arm 36 u wardly through the means 0 therod 33; t is release of the detents being'efie'cted automatically whenthewinding of a bobbin is completed whereby to permit the traverse-frame10 to swing away from the winding-spindle so that the bobbin may be morereadily dotfed therefrom. For thispurpose the rod 33 carries Elli anupright lever 43', see Fig. 2, which has an inclined upper end 44adapted to be engaged by the thread-guide 25 when the ide has been fedout to the end of the bob in. The lever 43 may be adjustedldngitudinallyof the rod 33 to cause it tobe engaged by the thread-guide25 when the latter has been fed outwardly along the traverse-bar 24 to apredetermined extent in winding a bobbin of the required length. J

As before stated, the traverse-bar 24 is reciprocated on thesupplemental frame 28 and, as shown in Fig. 2, the bar slides inbushings 47 driven into the bearings 26 and 27 on the frame. At theouter end of the frame 28 the bearing 26 is extended'to pro.- vide aguard for the end of the bar as it slides to its extreme of traverse. v

' Referring to Fig. 3, the arm 23 which connects the traverse-bar 24with the lower rod 18 has an offset or bent portion 48 fixedly held in aslot in the rod. At its upper end the arm 23 is bent around at 54 toencompass the traversebar 24 and is clamped thereto by means of a screw49. The screw 49 serves a" further purpose in providing means forattaching an element'of the guide controlling device to the arm'23, aswill be later explained. 5

Referring to Fig. 4, the traverse-bar is of usual construction, beingprovided with v screw-threads 50 cut into its side in eccen tricrelation to its :axis. The screw-threads are adapted to engagevcorresponding" threads on the interior of a cylindrical nut or sleeve 51which is rotated to advance or feed the threadrguide 25 longitudinallyof the traverse-bar 24. The sleeve or nut 51 extends between and isstraddled by the legs 52 and 53 of a bifurcated thread-guide holder 55,the ends of the legs being provided with bearings 56 and 57 swiveled onthe bar 24 to adapt the holder to" oscillate about the axis thereof. Thethread-guide proper may be constituted by a grooved, porcelain roll 58secured to the outer end of the holder by means of a screw or stud 59.

On the sleeve or nut 51 is a flanged disk 60. to the side of which isattached a; contact- 'wheel 61; The contact-wheel 61 has a flangedperipheral rim adapted to make contact with the surface of the windingon the bobbin whereby to turn the nut 51 on the bar. 24. The peripheryof the contact-wheel 61 makes contact with the base of the conical chaseof the winding at each rearward stroke be moved laterally todisengage'its threads from the threads onthe bar whenfit is re-'- quiredto release the nut to adjust the thread guide 25 to first position atthe st artof the winding. The nut 51 is normally held in eccentricrelation with respect to the axis of the bar 24, to maintain engagementbetween the threads on the bar and nut, by

means of a spring 62. The spring 62 has a coiled portion 63 with an arm64 reaching outwardly therefrom and bearing against the rim of the diskon the nut 51. The construction and arrangement of the parts lastdescribed is substantially the same as generally employed on bobbins andcop-winding achines in 'which the thread-guide is advancedlongitudinally of. the winding-spindle to deposit the yarn inforwardly-stepped courses laid on an inclined or conical chase.

As the thread-guide 25 is reciprocated longitudinally of thewinding-spindle 3- the thread-guide holder or arm 55 is oscillated aboutthe axis of the traverse-bar 24 to adapt the strand-feeding ordelivering portion of the guide to follow up and down the inclined chaseof the bobbin being wound. In previously used bobbin-windin machines ofthe present type thethread-gui e is designed to bear against the surfaceof the windingto direct its course up'and down theinclined chase of thebobbin. It has been found, however, that in Winding certain materials,such as silk, rayon and other delicate arns, the contact of the guide,with the sur ace of the bobbin-causes a chafing and abrasive actionwhich has a deleterious effect on the material. That is to say therubbing action of the guide on the bobbin chafes and roughens thematerial and spoils the finish of the yarn. It is therefore a primeobject of the present improvement to eliminate this hafing or abrasiveaction of the guide on the material, an to this end means are providedfor controllin the movement of the thread-guideto cause 1t to follow thechase of the bobbin Without contact thereon. In the present form ofconstruction of the invention the means for controlling the movement ofthe guide consists of a device for oscillating the thread-guide holder55 on the traverse-bar 24 during the reciprocatory motion of the guidein a certain predetermined path. The

guide-controlling device is operated from the traversing-meanssynchronouslytherewith. and a referred'form of construction of themechanism employed for this purpose will next be described. 7

Referring to Figs. 1,2 and 3, the thread guide controlling meanscomprisea rockable guiding-track 67, preferably constructed in Y the form of asheet-metal yoke orbifurcated frame as illustrated in perspectiveview inFig. 5. The frame 65 is constituted by a longitudinal bar 66, preferablyof angle-iron shape in cross section to provide an overhang- "ear s 69provided with holes 70 whereby the frame 65 may be 'rockably mounted onthe ing rail ortrack 67. Laterally-extending armsGS-at the ends of therail 66terminate ly bent forward end 78, through which the tion 74 isformed with a cam-slot ends of the bushings 47, before referred to asheld in the bearings 26 and 27 on the supplemental traverse-frame 28.

At the inner end of the frame the rail 67 is extended downwardl in anarcuatelyshaped triangular portion 74, see Fi s. 3 and 4, disposed inconcentric relation wit res ect to the axis of the traverse-rod 24 on wich the frame is swiveled. The dependin por- 5 inclined downwardly fromthe horizontal and adapted to receive a sliding stud or pin 76 proecting forwardly from an elbow-shaped arm 77 carried by the traverse-bar24; As herein shown the arm 77, illustrated in detail in Fig. 7, isprovided with a downwardpin 76 is riveted; and its rearward end is bentover to adapt it to overlie the top. and side of the traverse-arm 23which, as before explained, is clamped around the traverse-rod 24. Thedepen ing rearward portion 79 of the arm 77 is formed at its lower endwith a right-angled lip 80 projecting forwardly toward the traverse-arm23 and slotted at 81 to adapt it to straddle the sides thereof. In theportion 79 of the arm 77 is a hole 82 for receiving the screw 49 whichclamps the bent end 54 of the arm 23 to the rod 24. Lugs 73 rojectforwardly from the rearward. ortion 79 of the arm 77 to bear against theack of the arm 23 and when the screw 49 is screwed into place its headwill bind against this part of the arm 77 to clamp it securely to thearm 23, the slotted lip 80 preventing the arm 77 from turning or skewingout of position.

It will now be apparent that when the traverse-bar 24 is reci rocated inthe guideway of the frame 10 with the arm 77 moving therewith, the in 76 will be carried back and forth longitu many of the cam-slot 75 in theframe 65. As the slot 75 is inclined from the path of travel of the pin76 the sliding movement of the latterin the slot will have the effect torock the frame 65 on the axis of the traverse-bar 24. The alternaterising and falling motion of the rail 67 on the frame 65 is caused tooscillate the thread-guide 25 to carry its delivery point toward and awafrom the axis of the winding-s indle 3. This action is accomplishedthrong the means of a sliding connection between the guide-holder or arm55 of the guide 25 and the rail or track 67 of the frame 65. For thispur ose the guide-holder 55 is provided with a nger 83 rojectingrearwardly from its leg 53, see igs. 2, 3 and 4, and bent around to forma shoe 84which is adapted to hook around and straddle the rail 67 on theframe 65.

It will be understood that in the form of construction of the frame 65as shown in 5 the cam-slot 75 is inclined to the horizontal path of thepin 76 at a predetermined angle to cause it to impart to the frame 65the proper extent of rocking motion to carry the thread-guide 25 from aosition adjacent the outer circumference of the bobbin being wound, asillustrated in full lines in Fi 3, to a position contiguous to thesurface 0 the cylindrical barrel 0 of the bobbin-carrier, as indicatedby the dottedv lines in this view. To adapt the winding machine forwinding bobbins of different proportions, however, it is desirable thatthe controlling-device be provided with ad'ustable means for alteringthe extent of osciilation of the thread-guide, and for this purpose amodified form of the frame ma be employed as illustrated in Fig. 6 ofthe rawings. As here, shown the camslot or trackway 85 for the pin 76 isformed in a separate member or arm 86 which is pivotally connected tothe end of the rockable frame 87 by suitable means such as the screw 88.At its 0 posite end the slotted member 86 is rovide with an arcuate slot89 through whic extends a screw 90 screwed into an ear 91defiendingvfrom the rail 92 of the frame 87. y loosening the screw 90the outer end of the member 86 may be swung u or down on its pivot toadjust the inclination of the cam-slot 85 to regulate the extent ofthrow of the thread-guide 25 in accordance with requirements in windingbobbins of varying sizes or proportions. The frame 87 may be substitutedfor the frame 65 without other alteration in the construction of themachine and its method of functioning to control the oscillatorymovement of the thread-guide is the same as previously explained.

The method of operation of the complete machine is as follows: The papertube or other form of bobbin-receiver C is placed on the mandrel 8 ofthe winding-spindle 3 and the end of the yarn or other strand 3/ leadingfrom the source of supply, not herein shown, is attached to the tube inany suitable manner. The strand y may lead from a supply arranged belowor, as shown in the present drawings, it may draw downwardly from aswift, spool or the like placed above the machine in any convenientlocation. The strand 11 is carried around the porcelain roll 58 as itdraws to the carrier C on the winding mandrel whereby it will feed fromthe guide di rectly to the surface is to be performed.

Before starting the machine the traverseframe 10 is set in the ositionillustrated in Figs. 1 and 3 and 100(6d in place with the detent-lug 38on the latch 36 engaged with the shoulder 39 on the member 40. Thethread-guide 25 is then adjusted to'starting position by sliding it backonthe traversebar 24 until the center of its roll 58 alinessubstantially with the rearward end of the base 0 of the bobbin-carrierC, the adjustment of the guide to this position being accomplished byreleasing the nut 51 from the threads 50 'on the bar 24 in the manner aspreviously explained. The adjustment of the threadon which the winding 7guide 25 to starting position brings the contact-wheel 61 opposite thebase of the conical portion 0 of the bobbin-receiver C to adapt it tocontact with the first layers of yarn deposited thereon whereby, duringthe winding, the rotation of the contact-wheel will act to progressivelyadvance the layers of winding outwardly along the bobbin.

With the parts of the machine set in the position as above described theroll 58 of the thread-guide 25 will assume a position just clear of theouter circumference of the inclined portion 0' of the bobbin-carrier Cas indicated by full lines in Fig. 3. The machine is started to operatethrough the shifting of a clutch or other instrumentalities, not hereinshown, which are controlled through the manipulation of a starting-leveror handle 95 illustrated in Figs. 1 and 2 of the drawings. 'As power isapplied to the machine in this manner the winding-spindle 3 is driven torotate the bobbin-receiver C, and the cam 7 is rotated therefrom toreciprocate the rod 18 in the guideway 17 of the traverseframe 10. Therod 18 imparts reciprocation to the traverse-bar 24 through the mediumof the arm 23 connecting these-parts. As the traverse-bar 24 isreciprocated the threadguide 25 carried thereby is traversed back andforth lon itudinally of the windingspindle 3 with an extent of traversedefined by the throw of the cam 7 which is in proportion to the lengthof the chase to be wound on the tapered butt 0 of the bobbin-carrier C.Initially the thread-guide 25 will be traversed between the base end ofthe conical butt 0 and the point where its smaller end joins thecylindrical barrel 0. The guide 25 is thus caused to lay the yarn y inhelical coils deposited upon the conical surface of the butt 0' of thecarrier in the usual manner as practiced in winding bobbins of thepresent type.

As before stated it is desirable that the delivering point of the guide,that is the point from which the strand feeds to the bobbin, bemaintained in close relation with respect to the surface on which thewinding is being performed to insure the proper disposition of the coilsthereon. In previously'used machines of the present type it has been thepractice to allow the guide to contact with the surface of the windingto direct its course u and down the inclined chase of the bobbin, meansbeing usually provided for holding the guide against the bobbin undertension. In the present invention a prime object of the improvement isto prevent the contact of the thread-guide with the surface of thewinding while adapting it to follow the incline of the tapered chase onwhich the winding is being performed.

To provide for this control or regulation of the oscillating movement ofthe threadguide toward and away from the axis of the winding-spindle thepresent improved controlling-device functions as follows: With thethread-guide 25 at the rearward end of its throw or traverse the pin 76on the arm 77 will be positioned at the right-hand end of the cam-slot75 in the frame 65 as illustrated in Fig. 2 of the drawings. Now, as thetraverse-bar 24 is reciprocated from the cam 7 through the medium of thesliding rod 18 it will carry the thread-guide 25 outwardly or to theleft as viewed in Fig. 2. As the guide 25 is moved in this direction thepin 76 on the arm 77 which, as before explained, is fixedly attached tothe arm 23 extending between the rods 18 and 24, will he slid to theouter end of the cam-slot 75. It will be understood that the in 76 isheld by the arm 77 to move in a orizontal course parallel with the axisof the traverse-rod 24. Consequently, as the pin 76 rides along the camgroove 75 it will act to rock the frame 65 upwardly to correspondinglylift the. guiderail 67. This raising of the guide-rail or track 67 ofthe frame 65 acts through the finger 83 on the thread-guide holder 55 torock the latter on the axis of the rod 24 whereby to carry theguide-roll 58 inwardly from the position shown by full lines in Fig. 3to the position indicated by dotted lines in this view. In other words,the rocking of the frame 65 will oscillate the thread-guide 25 to causethe guide-roll 5.8 to follow down the inclined surface of the winding,but the relation between the parts are such as to prevent the roll fromcontacting with the'winding. As the guide 25 is carried back in theopposite direction the pin 76 slides towards the inner end of thecam-slot 75 to rock the frame 65 downwardly again into first position.During this returnthrow of the guide 25 the frame 65 is caused tooscillate the guide-holder. 55 to move the roll 58 up the incline of thechase while directing its course to prevent it from contacting with thesurfaceof the winding. In this manner the oscillating or to and fromotion of the thread-guide is effected synchronously with itslongitudinal traversing motion.

As the strand material is deposited on the butt 0 on the bobbin-carrierC it will build up in layers of crossing turns or coils, and eventuallythe contact-wheel 61 will be engaged by the winding at the inner end ofthe stroke of the guide 25. During this brief engagement thecontact-wheel 61 is rotated to a slightextent to turn the nut 51 which,through its engagement with the screw threads 50 on the rod 24, iscaused to feed the thread-guide outwardly on the bar. This action takesplace at the end of each rearward stroke of the thread-guide 25 so thatthe overlying courses of winding are advanced progressively along thereceiver C to build the bobbin in the usual manner whereby it is formedwith a cylindrical body and of the machine.

a tapered or conical nose-end as indicated by t e dot-and-dash lines inFig. 2. It will be understood that as the threaduide 25 feeds outwardlyon the traverse-r0 24 the bent portion or shoe 84 on the finger 83slides along the track or rail 67 to maintain the connection between therockable frame and the thread-guide 25.

After the thread-guide 25 has been fed outwardly on the traverse-bar 24to a sufficient extent to comfilete the bobbin to the required length,fina y, at the outward traverse of the guide, the leg 52 of theguideholder 55 makes contact with the inclined end of the arm or lever.43 to rock the rod 33. The rockin of the rod 83 releases thedetent-latch 36 from the locking member 40 and thus the traverse-frame10 is unlocked to allow it to swing back under the action of gravity toremove the contact-wheel 61 from further contact with the winding. Atthis juncture suitable instrumentalities, not herein shown, are broughtinto action to disconnect the drive of the machine to arrest the windingoperation, whereupon the comileted bobbin may bedofi'ed from the man rel8 and a new tube or receiver placed thereon.

I am aware that it has before been pro osed.

to oscillate the thread-guide of a bo binwinding machine-to direct itscourse in parallel relation with respect to the inclined chase of thebobbin while holding it from contactin with the surface of the windin.Such a fbrm of construction is shown and described in the pending aplication of J. A. Anderson, Serial No. 281,5 1, filed May 29, 1928, nowPatent No. 1,819,695 Aug. 18 1931, but in the machine of thisapplication the oscillation of the thread-guide is effected through theuse of a crank or eccentric rotatedfrom a going part In the presentinvention the use of such a crank-motion or eccentric for oscillatingthe thread-guide is dispensed with, whereby to simplify the constructionof the controlling-device and further to render it more positiveanddirect in o ration. In the present invention thelongitudinaltraversing movement of the thread-guide is employed to effect andcontrol the actuation of the frame which oscillates the threadaids andthrough this arrangement a num er of elements are eliminated, themechanism simplified and rendered more compact, and other advantagessecured which will be readily apparent to those skilled inthe art.

In accordance with one form of construction of the invention as hereinshown and described the oscillating device for the threadguide is madeadjustable to regulate the extent of movement of the thread-guide and tocontrol its range of action for bobbins of different proportions orsizes. This adjusts ing-means is extremely simple in structure,convenient to set and proof against derangement and getting out oforder. The

of, a winding-spindle,

mechanism of the whole device, in fact, is reduced to the utmostsimplicity while being im roved in efiiciency of operation.

t is further to be observed that the camtrack on the rockable frame andits follower actuated from the reciprocating motion of the thread-guideare susceptible of a change in their re ation or, in other words, areversal of the parts without affecting their method of operation forthe purpose explained.

While I have herein described and illustrated the improvement as appliedto use with a certain type of winding machine, and as embodied in areferred form of construction, it is to be un erstood that variousmodifications may, be made to ada t the device to other forms of windingmac ines, and also in the structure and arrangement of its parts,without departin from the spirit or sco e of the invention. herefore,without limiting myself in this respect, I claim:
